Glucocorticoids have remained important anti-inflammatory agents in the treatment of chronic kidney disease (CKD).However,the use of glucocorticoids can invoke or enhance insulin resistance,which is closely associated with renal injury and serves as an independent risk of the occurrence and progression of CKD.On the other hand,CKD patients may have insulin resistance,which hampers the use of glucocorticoids in these patients.

The ion beam bioengineering study articles for 1994 -2003 years were retrieved, the research material and the level of the research, magazine, the ion source and the fund source were analysed and counted. The results indicate that the ion beam bioengineering of China get a fast development under the support of the nation and the local government and college. The development in the field of microbe is the fastest. in 21st century, the local government and colleges gradually enlarge the support of the ion beam bioengineering, some articles are under the support of enterprise researcher and fund. The contents of these articles mainly about application study. After analysing the data, the future of ion beam bioengineering of China was forecasted.

Objective To compare the prognosis effect of different Helicobacter pylori (Hp)eradication methods in patients with chronic gastritis.Methods One hundred and twenty patients with chronic gastritis diagnosed by gastroscopy and pathology examination were divided into sequential therapy group (36 cases),triple-combined therapy group (34 cases),Hp positive without eradication group (30cases) and Hp negative group (20 cases) according to the Hp infection status.All patients were followed up by gastroscopy,biopsy and rapid urease test before and after therapy.Results The Hp eradication rate in sequential therapy group was 94.44％ (34/36),in triple-combined therapy group was 73.53％ (25/34),and there was statistical difference (x2 =5.775,P =0.016).The symptoms scores and gastroscopy scores after therapy in the four groups were significantly lower than those before therapy,and there were statistical differences (P ＜ 0.05).The symptoms scores and gastroscopy scores after therapy in sequential therapy group were significantly lower than those in triple-combined therapy group,and there were statistical differences (P ＜0.05).The symptoms scores and gastroscopy scores after therapy in sequential therapy group,triple-combined therapy group and Hp negative group were significantly lower than those in Hp positive without eradication group [(0.84 ± 0.60),(1.34 ± 0.59),(1.49 ± 0.62) scores vs.(2.98 ± 0.54) scores,(0.47 ± 0.37),(0.83 ± 0.35),(0.96 ± 0.75) scores vs.(1.22 ± 0.40) scores],and there were statistical differences (P ＜ 0.05).Conclusions The Hp eradication rate of sequential therapy is higher than that of triple-combined therapy.The two therapy methods can both improve the symptoms score and gastroscopy score,but the symptoms after sequential therapy are relieved faster compared with triple-combined therapy.

Multiple organ dysfunction syndrome(MODS),a hot topic worldwide,has made rapid progress with nigh mortality.MODS in pediatrics versus MODS in adults are similar but different.Due to special age-related physiological characteristics.It is difficult to carry out randomized controlled clinical study compared with adults.Diagnosis and treatment of pediatric MODS can only be obtained with reference to adult MODS.This study reviews on the epidemiology,clinical scoring system,pathogenesis,clinical features and treatment of MODS in pediatrics.

Objective To investigate the efficiency and safety of stent implantation for severe pulmonary vein stenosis after radiofrequency ablation (RFA)of atrial fibrillation.Methods The clinical date of 231 cases with atrial fibrillation received RFA treatment were analyzed retrospectively.Eight cases were confirmed with severe pulmonary vein stenosis after RFA by CTA.The stents were implanted after angiography.Results All the 1 9 serious pulmonary vein stenosis from the 8 patients were treated stent implantation.The degree of pulmonary vein stenosis,trans-stenotic gradient,mean pulmonary pressure and the level of BNP were significantly decreased after treatment (P <0.01).The minimal diameter of the stenosis was significantly increased compared with preoperative (P <0.01).Six months after stenting,2 patients in 4 pulmonary veins were stenosis.The stenosis was successfully di-lated by repeated interventions with balloon dilation.There was no stenosis appeared in the patients after the repeated interventions with balloon dilation for 3 months.Conclusion Stenting implantation was a feasible and safety method for severe pulmonary vein stenosis after RFA.

6.0,and the expression of CD62P in groupⅠand Ⅱ(32% and 36%)was significantly higher than in control group(28%).However,when the three groups were stored until day 7,all in vitro parameters determined of PCs were better maintained in control group than in the other two.Conclusions The 5-day storage of PCs in additive solution with 50% or 20 % plasma is feasible in terms of the in vitro function in platelet count and pH,however,PCs storaged in additive solutions are more easily activated.

Hutchinson-Gilford progeria syndrome (HGPS) is an early onset severe premature aging disorder due to a point mutation in LMNA gene which encodes nuclear lamin A/C. The mutation activates a cryptic splice site within exon 11 of LMNA, resulting in a 50-amino acid in-frame deletion in prelamin A. However, it is not clear how the mutation in a structural protein under the nuclear envelope could give rise to premature aging phenotypes. Recent studies showed that various abnormalities have been found in nuclear structures and functions of HGPS cells, mainly including progerin accumulation and nuclear morphology abnormalities, altered nuclear mechanical properties, changes of histone methylation patterns and epigenetic control, gene misregulation, p53 signalling activation, and increased genomic instability. Two hypotheses recently emerged in the explanation of the pathogenic mechanisms contributing to HGPS. No effective clinical intervention has been developed so far for HGPS. Several fascinating therapeutic strategies have recently been provided, such as farnesyltransferase inhibitors, antisense oligonucleotides and RNA interference. HGPS has been considered to be a model for studying the mechanisms responsible for normal aging. This study will help to elucidate the physiological functions of lamin A and nuclear envelope, together with their roles in normal aging process and diseases.
